Abstract

A driver assistance system for motor vehicles, having a velocity regulation function for regulating the velocity of the subject vehicle to a nominal velocity, and having an adjacent-lane monitoring function, characterized by a turning assistance function which, when the velocity regulation function is active and an incoming signal indicates an imminent turning process that requires crossing an adjacent lane, monitors the traffic in the adjacent lane with the aid of the adjacent-lane monitoring function, and, as a function of locations and velocities of traffic participants in the adjacent lane, determines a spatial and temporal window for moving into the adjacent lane and adapts the nominal velocity to this window.

Claims

1. A driver assistance system for a motor vehicle, comprising:

a velocity regulation function arrangement for regulating a velocity of the subject vehicle to a nominal velocity;

an adjacent-lane monitoring function arrangement;

a turning assistance function arrangement that, in response to an incoming signal indicating an imminent turning process that requires crossing an adjacent lane, monitors a traffic in the adjacent lane with the aid of the adjacent-lane monitoring function arrangement, and, as a function of a location and a velocity of a traffic participant in the adjacent lane, determines a spatial and temporal window for moving into the adjacent lane and adapts the nominal velocity to the window.

2. The driver assistance system as recited in claim 1, further comprising a navigation system including a route planning function arrangement for generating the signal that indicates the imminent turning process.

3. The driver assistance system as recited in claim 1, where the velocity regulation function arrangement includes an adaptive cruise control function for regulating a distance to a vehicle driving ahead in a lane of the vehicle including the driver assistance system.

4. The driver assistance system as recited in claim 1, where the adjacent-lane monitoring function arrangement includes a blind-spot detection function.

5. The driver assistance system as recited in claim 1, where the adjacent-lane monitoring function arrangement includes a lane change assist.

6. The driver assistance system as recited in claim 1, further comprising at least one radar sensor for monitoring a space next to and behind a vehicle in the adjacent lane.

7. The driver assistance system as recited in claim 1, further comprising:

an assistance function arrangement for recognizing a speed limit, wherein, as a function of a situation, the turning assistance function arrangement is adapted for increasing the nominal velocity to a maximum value that is determined by the speed limit.

8. The driver assistance system as recited in claim 1, where the turning assistance function arrangement is adapted for outputting a lane change recommendation to a driver.

9. The driver assistance system as recited in claim 8, further comprising:

a lane keeping support function arrangement; and

a haptic signal output system that acts on a steering wheel of the vehicle and that is utilized by the turning assistance function arrangement for outputting the lane change recommendation.
